SMF117 2rs Bearing Product Overview & Core Advantages
The SMF117 2RS is a miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Featuring stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. The integrated rubber seals (2RS) provide effective protection against contaminants while retaining lubrication, making it suitable for applications demanding low maintenance and long service life. Its compact design (7mm bore, 11mm OD, 3mm width) makes it ideal for space-constrained assemblies.
